AFIL sensor 1 Citroën Peugeot 9647742280

Description

Lane driving sensor AFIL number 1 for CITROEN PEUGEOT
cars
There may be a broken screw that holds the unit to the undercarriage – must be unscrewed

Part description

This AFIL sensor (Lane Driving Sensor) number 1 is designed for Citroën and Peugeot cars. It is an electrical component from the group of sensors/sensors, often searched by OEM number 9647742280. If you’re troubleshooting a lane keeping system or need to replace a damaged sensor, this is the right type of part that makes sense to choose based primarily on the label and codes.

Practical note from disassembly: with this type of part, it may happen that the screw holding the unit to the undercarriage is snapped – in this case, it is necessary to count on drilling it out.

Installation recommendations

Generally/typically for the AFIL sensor (electrical sensor), the exact procedure may vary depending on the specific design of the car and mounting. Below is a practical procedure that focuses on safe replacement and minimizing the risk of damage to connectors and wiring.

1) Before assembly (checks)

• Compare the part numbers on the label (min. 9647742280 + possibly 603.011 / 6590W1) with the old sensor.
• Check the condition of the connector (bent pins, oxidation, plastic cracks) and the grommet/wire harness at the connection point.
• Inspect mounts and seating surfaces – for cracked mounts or deformations.
• Be aware that the mounting screw may be notched (see note in description) – be prepared to drill.

2) Necessary tools and materials

• Basic set of hand tools (ratchet/wrenches according to design, screwdrivers)
• Electrical cleaning products (e.g. contact cleaner), cloth
• Tools for releasing connectors (plastic crowbar)
• If the screw is damaged: kit for drilling / screw extractors (depending on the situation)

3) Step-by-step assembly procedure

1. Turn off the ignition and disconnect the battery (for electrical parts, you minimize the risk of short circuits and errors in the system).
2. Ensure access to the sensor according to the design of the car (removal of necessary covers/undercarriage, etc. – according to the specific car).
3. Clean the area around the part so that dirt does not get into the connector or on the contact surfaces.
4. Disconnect the electrical connector carefully – do not pull on the cables, release the connector lock.
5. Enable sensor attachment. If the fixing screw is notched, proceed safely: prepare the center, choose a suitable drill and drill in a controlled manner to avoid damaging the surrounding parts.
6. Disassemble the old sensor and compare it with the replacement part (shape, connector, numbers).
7. Clean the bearing surface and check that the attachment is not deformed.
8. Install the sensor in its original position and secure it appropriately for the mount.
9. Connect the connector – make sure it is properly seated and secure.
10. Put back any covers/parts that were removed for access.
11. Connect the battery.
12. Turn on the ignition and verify that the system behaves as standard (indicators/messages depending on the car’s equipment).

• 4) Post-assembly checks and test drive/function verification

  • Visual check that the wiring is not rubbing anywhere, is not pinched and the connector is firmly secured.
  • Verify the function of the system during normal driving in conditions where AFIL is typically activated (depending on the car’s equipment).
  • If diagnostics are available, check for any sensor and power/communication related errors stored.

  5) The most common assembly mistakes + how to avoid them

  • Damage to the connector/pins when disconnecting – always release the fuse and do not pull on the cables.
  • Poorly secured connector – after clicking, check that it holds and the fuse is in the correct position.
  • Underestimation of a notched screw – when drilling, work in a controlled manner, protect surrounding parts and wiring.
  • Assembly without part number comparison – always check the OEM and other codes listed on the label.

  Reasons why the part is damaged

  • Moisture and oxidation in the connector or in the wiring (or repeated leakage of water/dirt in the mounting area).
  • Mechanical damage from stones, dirt or improper handling during disassembly/assembly.
  • Damage to the cabling (abrasion, pinching, broken wires), which will be reflected in signal dropouts.
  • Poor attachment and subsequent vibrations – they can gradually damage the holder, the connector or the sensor itself.
  • Notched/damaged mounting screw and violent disassembly – risk of damage to the sensor body and surrounding parts.
